SINTON® S is a self-adhesive, flexible insulation board for acoustic decoupling of concrete components that are flush with the staircase wall. SINTON® S is bonded to the face of the structural element when used on precast parts. The panel is fixed to the staircase wall when used for in-situ concrete. Joints must be taped. When used between a staircase and staircase wall, the impact sound insulation board SINTON® S corresponds to building material class B1 according to DIN 4102-1 (see report no. 2302/162/21 of MPA Braunschweig). The fire resistance class of the staircase results from the surrounding reinforced concrete components as SINTON® S is not statically relevant.
